Homeschool World Forum

I am doing research on the successes of homeschooling. I also wonder if there is data on college attendance, high school graduation and other standards. Background to this is the book by the late author Ralph de Toledano called Cry Havoc. Ralph was a good friend of mine, and spent years fighting the cultural decline in education. Is there a comprehensive history of homeschooling? Most of the books out there are either suggestions on curriculum, or biased articles, blogs, etc. that oppose the program.
